Enum linter
===========
Enum linter checks:
- incorrect type or basic literal is assigned to enumerated type value
- switch clause is not exhaustive (in progress)
Example
=======
```
type Enum int
const (
Apple Enum = iota
Pear
Banana
)
...
var f Enum
f = Apple
f = 10
f = Enum(55.)
fmt.Print(f)
ch := make(chan int, 1)
ch <- 123
chEnum := make(chan Enum, 1)
chEnum <- 321
m := map[string]Enum{
"aaa": 1234,
"bbb": Banana,
}
s := S{
Fruit1: 88,
Fruit2: Pear,
Fruit3: f,
Fruit4: Enum(GetInt()),
Fruit5: Enum(<-ch),
Sub: subS{
Fruit: 11,
},
SubSub1: subsub{
Sub: subS{
Fruit: 22,
},
},
SubSub2: subsub{
Sub: subS{
Fruit: Enum(44),
},
},
}
if f == Enum(22) {
fmt.Println("equal")
}
if s.SubSub2.Sub.Fruit == 1 {
fmt.Println("equal")
}
```
Run
===
```
$ enumlinter -type Enum ./enum.go
```
